Application filed July '13, 1912, Serial No; 209,262.

, agcitizen of the United States, and a resident of Louisville, in the county of Jefferson and State of Kentucky, have invented a new and. Improved Pipe-Support, of which the following is a fall, clear, and exact description,

' u invention is an improvement in travcling supports for pipes, and has for its object the provision of a safe and sample device of the character specified, for supporting heating and power pipes, wherein means is. provided for permitting the expansion and contraction of'the pipes lathe pipe or to the support.

Beferrin to the drawings forming a par hereoft-F1gnre 1 is a side view of-the support with the pipe in place, Fig. 2 is d tion on the line 2-.2 of Fig. 1, Fig. 31s a erspective view of the base of the support, igi, a is a perspective view of the carrier withthe pipe removed, and Fig. 5 is a verticallongitndinal section of the pipe and support.

.lhe present embodiment of the invention comprises a base or cradle, consisting of a substantially rectangular frame, composed of end members 1 and side'members 2, the

and members extending beypnd the sidemembers at each side of the carrier as shown at 3. The extended portions?) of the'end,

members are rounded on their under faces as shown at a.

Each of the side members 2 isslotted as shown at 5, for the sake of lightness, and while the upper edges of the side members are flush with the upper edges of the end members, the said side members are cut away on the under side of the base as shown more particularly in Fig. 5. The end members are connectebetween the side members by a pair of rack bars 6, each rack bar being integral at its ends with the end members, and the teeth of each rack bar are in register with the teeth of the ad- 'he rack bars are also integral jacent bar. I, with the side members at their outer sides for the salts of strength as shown in Fi 2..

A slot 7 te -provided between the rack ars the under faces of the rack bars are finish. with the lowest portion of the ends 3 of the and members.

without injurysec- A movable support, carriage, or saddle is provided for receiving the pipe 9, the said pipe having the usual non-heat conducting,

covering 10, secured thereto by straps 11. The carriage. is concave on its upper face to fit the covering as shown at 12, and each side edge thereof is provided with spaced openings or slots 13 for permitting the con: motion of the-ends of holding wires. 14.

Each of the holding wires 18 connected at gits ends with an opening 13, the said wires passing over the covering to secure the pipe {to the carriage; T with a central longitudinally extending rib 15.011 its lower face and with a series of rack iteeth -16 at each side of the rib, the said iteeth being spaced to correspond with the iteethof the rack bars 6.

between the carriage and the rack bars, each wheel meshing with, a rack bar 6 of the base andwith the adjacent series of teeth 16 .of the carriage. The rollers are connected by a shaft 20, and the inner face of each roller is flush with the inner edge of the rack barwith whichit engages. ll he rib 15 extends between the wheels as shown in A pair of toothed heels'll) are arranged he carriage is provided Figs. 1 and 2,, and. the arrangement of-the rack bars 6 with respect to the base provides a stop at each end of each rack bar. The said stop is the inner face of the adjacent lend member 1, and the said faces limit the jtravel of the wheels. The carriage is connected directly with the pipe by means of a block or key 21, arranged in a recess 22 at the center of the upper face of the cal--- riage, and having at its upper end an areshaped bearing plate 23,.for ehgaging the pipe. The covering 10 of the pipe is cut away to receive the key and the bearing plate as shown in Figs. 2 and 5.

' The rollers may be secured to the shaft 20, in any desired manner, and the said rollers travel in a pocket or depression in the cradle. It will be evident that the .-upper surface of the carriage or saddle come-'- spends with the c .rvature o-f the pipe so as to 'fit the said pipe closely. When the pipe 15 not covered, the key or block 22 and I the bearing plate 23 are removed. The object of the key or block is to prevent bend- :ing of the 'ipe by compression of the cover- I .ing. The trey rbloclrengagesthe pipe dl'.

. pocket or depression of the cradle, prevents any binding or skewing of the parts with respect to each other. The pipe must travel longitudinally and cannot move laterally. The provision of duplicate rollers, rack bars and series of teeth lightens the device,'as a whole, and permits dirt or leakage to fall through the slot- 7 without interfering with the operation of the device.

It will be obvious that the carriage or saddle might be divided into a plurality of beds for carrying a number of pipes side by side without departing from the spirit of the invention. The rib 15 also prevents the saddle from creeping laterally, holding it in itsproper position with respect to the rollers With the present construction the weight of the pipe and its resistance to thrust is distributed evenly throughout the extent of the pipe. The cradle or carriage cannot shift from its position laterally neither. can it rock, and as a whole, there is a minimum of weight for the necessary strength.

It is obvious that many changes might be made in the construction without departing from the spirit of the invention. as specified in the appended claims.

It will be understood that the gear wheels above mentioned are preferably integral, that is, the wheels. are in fact a roller having aseries of teeth at each end separated by the groove for receiving the rib. It is obvious however, that the wheels may be separate if desired.
